There is never a classy version of the pyro, why cant a pyromaniac be civilized every once in a while? The design was mine, except Valves Gas Mask and Axtinguisher. This was worn to Matsuricon, though i did not carry the axe that day. (I just wanted more pictures of it, but it turned out nice)

I made it myself, was pretty simple, just a round PVC end cap with a round piece of wood to cover the hollow bottom (and some sanding), then screwed into the mask. But if you get the mask be sure to get the right size for you
